Application filed June 4,

To all whom it may concern Be it known that I, THOMAS J. KEHOE, a citizen of the United States, residing at Toledo, in the county of Lucas and State of Ohio, have, invented certain new and useful Improvements in Radiators, of which I declare the following to be a full, clear, and exact description.

This invention relates to removable closures, and particularly closures for use in closing the filling openings in radiators for motor vehicles.

The principal object of my invention is to provide a removable closure which is nor-- mally held in position covering the openings by means of spring tension. Another object of my invention 1s to provide a radiator cap construction such that the cap is permanently attached to the radiator, may be swung to open position without disconnecting any part, and is resiliently held in open positlon.

Further objects, and objects relating to details of construction and economies of manufacture, will definitely appear from the detailed description to follow.

I accomplish the objects of my invention by the devices and means descrlbed in the followin specification. My invention is clearly efined and set forth in the appended claims. A structure constituting a preferred embodiment of my invention is illustrated in the accompanying drawing, forming a part of this specification, in which:

Figure I is a fragmentary, front elevation of an automobile radiator provided with a radiator cap embodying my invention.

Figure II is an enlarged, sectional view, taken on the line IIII of Fig. Kand showing the ea in closed position.

Figure II is a view similar to Figure II,

but showin the cap in open position.

Figure I is a detail, sectional view, taken on the line IV--IV of Figure III, showing the hinge connection.

Figure V is a detail, sectional view, similar to Figure II, showing a modified form of my invention.

Fi re VI is a view, similar to Figure V, but s owin the cap in open position.

Figure II is a detail, fragmentary view in side elevation, showing a portion of the locking and tensioning means.

1917. Serial No. 172,755.

The lower end of said stem 4 1s bent at sub-.

stantially right angles to the body thereof and is connected to the side of the nozzle 2 by means of the pintle 5, which passes through the end of the stem 4 and is carried by the yoke 11 attached to the side of the nozzle by the rivets 12. The stem 4 extends upwardly through the cap 3 and the washer 6 is secured to the upper end of the stem by the screw 7 Spring 8 is compressed between the washer 6 and the upper end of 11 cylindrical boss 9 which is formed on the cap 3. A guard or housing 10 surrounds the upper end of the stem 4 and the s ring 8, and is threadedon to the cylindrical boss 9. This guard serves to house and protect the stem 4 and the spring 8, and also serves as a handle by which the top may be swung to one side when} the filling opening is to be uncovered,

When the cap 3 is in the position shown in Figure II, the spring 8, actin on the cap 3, serves to normally press-it downwardly in engagement with the rim 2 of the nozzle 2, so that the cap is yieldingly held in engage'ment therewith. Cap 3 can be tilted or moved laterally against the tension of the spring 8 and'when the cap has been, moved to one side to uncover the opening, the spring will tend to hold the" cap 3 against t e side of the nozzle 2, as shown in Figure III. The co-operative action of the spring 8 and bent stem 4 results in the closure being positively held in either 0 orv closed position, since,--as shown in igure III when the stem istilted from its normal upright osition, the base of the closure is pressed rmly against the outer side of the nozzle 2 and the closure held at one side of the nozzle opening, while, as shown in Figure II, when the stem is in upright position, the closure is clamped firmly upon the rim tached to the radiator and is always held in.

yielding engagement with the nozzle so t t there is no chance for it to rattle or work loose.

In Figures V to VIII inclusive, I have shown a modified form of my invention in which a downwardly curved yoke 14 is secured inside the nozzle 2. This yoke is provided with a central slot 15, as appears from Figures VI and VIII. The cap 17 has the stem 16 slidably mounted therein, and is provided at its upper end wit-h a handle 22. Yoke 20 is fastened to the cap 17 and provided with a central opening through which the stem 16 passes and the spring 21 is compressed between said yoke 20 and a shoulder 19 formed on the stem 16. A bar 23 extends downwardly and laterally from the stem 16, passing through the slot 15 in the yoke 14, and said bar is provided at its upper end with shoulders 24 which are adapted to engage notches 25 formed in the edges of the opening 15 in the yoke 14. A flat leaf spring 26 is secured to said bar 23 by the screws 27 and is adapted to engage the edge of the opening 15, when the top is raised to open position, the end of said spring being rovided with a laterally bent portion 28 w ich serves to hook the edge.

of the o ening 15 to prevent complete removal o the cap. In igure VI the top is shown in its open position and, to close the opening, the ca is moved into osition 'over the o ening an the stem 16 is orced downward y until the shoulders 24 are below the yoke 14. The handle'22 is then given a partial turn which brings the shoulders 24 Into engagement with the notches 25 in the edges of the opening 15, and the handle is then released, the spring 21 bringing the shoulders 24 into positive engagement with the yoke' 14 so that the cap is ieldingly but positively held in position. 0 remove the .010- sure it is merely necessary to'depress the handle22 against the tension of spring 21 and to give the handle a 'partialturn' so as to bring the bar 23-into alignment with the slot 15, when the spring 21 will force the cap and the stem 16 upwardly.

have shown my invention embodied in a radiator cap construction, but it will be evident that thisinventionis applicable equally as well toother constructions in which it is desirable to provide a closure'whichis held in position by springtension and permanentlyattached to the part which. it serves to closeso that it can not become separated therefrom and lost. and therefore, I do not desire that'my claim should be considered as limlted to a radiator cap construction.

- scribed, is desirable from many standpoints,

but I am aware that other embodiments of the invention are possible and that the embodiment here shown. may be varied considerably without departing from the spirit of my invention, and, therefore, I desire to claim my invention broadly, as well as specifically, as indicated by'the appended claims.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:

1.
